Well, I thought it was impossible. In all my experience (which, mind you, isn't THAT much) I've never seen such clarity on a fast, wide-open lens. Usually, it's bokeh out of the ass at anything less than f/2.0, and at a distance of less than, like, 10 feet. Depth of field would be tiny with most fast lenses. It's a 24mm wider angle lens, so while it looks like he's further away, he's probably not much further than the aforementioned 10 or so feet.

But regardless, it's Leica glass, and apparently, it blows my preconceived notions of lens performance out of the water.

No. Have you ever used a wide aperture prime? It's blur city. The fact you can even make out the background at all means its a considerably smaller aperture. Look down a bit, you can see Chris said that too. He used a manual lens with no electronics.
